MUSIG-SHEET-TRAVIEL-CONTROL PEBFOBATIONS.

Specification of Letters Patent.

Patented July 9, 1918.

Application filed December 17, 1917. Serial No. 207,640.

- following is a specification.

Prior art of control of the rewind and repeat travel of a music sheet from perforations therein originated in M. Gally, #222,030, November 25, 187 9, and developed in Arno #596,768, January 1, 1898, but'in the first instance foot or hand power was used, and although in Arno an electric drive was employed, he provided for his electric motor being stopped from a perforation in the sheet Whenever it had returned to its commencement end. Thus in neither of these devices did it make any difference as to what positions the rewind and repeat perforations were located relative to the edge of the music sheet, and no such transverse location was set forth by either of these inventors, but when no automatic stop perforation is employed for stopping the drive motor, or when foot power is employed with such automatic controls by the rewind perforations 1 or 2, and repeat perforation 3, especially when the front end of the music sheet a is slanted away from its edges at its commencement end 5, which is usually so, and has a means as 6 for attaching to the take-up device of the music player, it does become important to locate the repeat perforation 3 nearer to an edge 7 of the music sheet 1 than the distance of any rewind perforation 1 from the same edge of the music sheet, or a rewind perforation 2 from the other edge 8 of the music sheet 4, for unless the repeat perforation 3 is nearer to an edge of the sheet than the rewind perforation 1 or 2, the corresponding apertures of the tracker bar 9 controlled by the said perforations would be in such relation to the slanted edge or edges of the sheet as to allow the rewind aperture 10 or 1 to remain open later than the repeat aperture 11 as such a slanted end. music sheet was drawn over said tracker, with the ul t the ew nd pull on the sheet would prevent the user from completing its placing in the apparatus and attaching to the take'up device of the player for the forward travel of the sheet at to play the note perforations 12, all which is avoided by the novel positioning of the rewind and repeat perforations as above described, and as set forth in the accompanying drawing, and being what is claimed as my invention, which is 1. A music sheet having perforations for notes alined therein in several rows longitudinally of the sheet, a perforation in another alinement to eflect the shifting to the rewind travel of the sheet, and another perforation, in another alinement than any of the aforesaid perforations to effect the shifting to the repeat travel of the sheet for replaying, the said perforation for repeat travel being nearer to an edge of the sheet than is the perforation for rewind travel.

2. A music sheet having perforations for notes alined therein in several rows longitudinally of the sheet, a perforation in another alinement to effect the shifting to the rewind travel of the sheet, and another perforation, in another alinement than any of the aforesaid perforations, to effect the shift ing to the repeat travel of the sheet for replaying, the said repeat perforation being nearer to one edge of the sheet than the said rewind perforation is to the other edge of the sheet.

3. A music sheet having perforations for notes alined therein in several rows longitudinally of the sheet, a perforation in another alinement to effect the shifting to the rewind travel of the sheet, and another perforation, in another alinement than any of the aforesaid perforations to effect the shifting to the repeat travel of the sheet for replaying, the said perforation for repeat travel being nearer to an edge of the sheet than is the perforation for rewind travel, and the forward end of the said sheet being slanted away from its edges at that end.

4. A music sheet having perforations for notes alined therein in several rows 1ongitudinally of the sheet, a perforation in another alinement to effect the Shifting to ill? re- Wind travel of the sheet, and another perthe sheet, and the forward end of the said foration, in another alinement than any of sheet being slanted away from its edges at the aforesaid perforations, to effect the shiftthat end.

ing to the repeat travel of the sheet for re? ROBT. A. GALLY. 5 playing, the said repeat perforation being lVitnesses:

nearer to one edge of the sheet than the said P. J. HENGGE,

rewind perforation is to the other edge of NORMA KLEIN.
